There’s a new “Find Items” dialog which allows you to find items by typing in part of their name. This dialog can be brought up using a customizable shortcut (set to Alt-F by default), or by clicking the new magnifying glass icon on the inventory bags next to the “x”. The dialog will also search in vendor windows, scrolling the window as appropriate. The vendor windows also have the magnifying glass icon next to the “x”.

The items are highlighted using the “New Item” Overlay, and the highlights go away when the “Find Items” dialog is closed. You can also search by using the “/fi” player command.
